Load up "Comedy Central Presents" episode 213: Sean Cullen, and fast forward the slider to exactly 9:23 into the show. I'd say more but it would diminish effect of the content - lasts about two minutes.
I searched all over for it because it's a pretty funny song. Most of his other songs are on iTunes and Amazon MP3 but not this one yet. I would have bought the album just to rip this and mix it into my regular rotation to mess with people and get a good laugh.
